1,401,298. Specification of Letters Patent.

To all whom. it may concern Be it known that I, BERT R. WILLIAMSON, a citizen of the United States, residing at Fairfield, county of Somerset, State of Maine, have invented an Improvement in Bundhng-Machines, of which the following description, in connection with the accompanying drawing, is a SPBCIHCMJIOII, like characters on the drawing representing like arts. i

p This invention relates to a machine for bundling articles and is especially designed for use in puttin up bundles of pulp or paper pie lates, utter dishes, and similar articles. uch articles are usually stacked in piles or rolls of the desired number, as five hundred, wrapped in heavy paper, and tied with twine running longitudinally and transversely around the pile or roll.

A machine for this purpose is disclosed in the patent to M. L. Keyes No. 921,256 granted May 11, 1909, andthe present invention is an improvement thereon.

The object of the present invention is to simplify the construction and operation of a machine of thisty '1 Theobject of the invention isfurther to provide in such' a: machine quick acting means for operating the movable head to compress the articles.

These and other objectsand features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims. I; f

The drawings show the complete bunmachine embodying a preferred form of the invention. a

.In the drawingsa Figure 1 is a view in side elevation the machine.

Fig. 2 is a view in side elevation and par tially in vertical cross section of the right hand head support, head, and means for operating the head. i

Fig. 3 is a view in end elevation showing the upper portion of the right hand end of the machine. I

The supporting standard of the machine comprises a bed 1 extendin longitudinally at a suitable height from t e floor and of any desired len the len h of t the mac ine. This bed is conveniently supported near the left it is used.

a mounted from and capable of similar adjustment th determined in general by a e bundles to be formed in hand end by a pair of legs 2 mounted on casters 3, and near the right hand end by a single leg 4. This provides an easy means by which the machine may readily be moved about the room where This may be done by lifting the end of the machine having the single leg 4, and then rolling it along on the casters pair of oppositely disposed heads are both, of these heads are longitudinally adustable upon the bed. Preferably also the eads are carried in head supports and the longltudinal adjustment is secured by adustmg the head supports upon the bed.

The right hand head support 5 has a depending rib 6 fitting in a longitudinal groove in the bed whereby the head support 1s :guided in its longitudinal adjustment. h clamped in position e head support is by a bolt 7 extending through a transverse recess in the bottom of the head support and provided with oppositely disposed clamped blocks 8 beveled as indicated in Fig. 3 above and below the clamping bolt to engage corresponding bevels on support and the top of the bed. The left the baseof the head hand head support 9 is similarly constructed by means of a similar clamping bolt 10. It will thus a be seen that by loosening the clamping bolt may be moved along either head support the bed to the desired position and by tight} the bed, and one, preferably suing the clamping bolt may be locked in its adjusted position. Either or both of the clamping bolts may be provided with a handle 11 by means of whichit may be readily turned to clamp and unclamp.

The heads which are carried by the respective head. supports are preferably of the skeleton like form shown in the patent to Keyes above referred to and conform in general to the exterior surfaces of the ar-.

ticles, such as pie plates, to be bundled. The left hand head 12is shown as adapted to fit the concave surface of the article at the left hand end of the bundle, and is carried upon a spindle mounted in the barrel of the head su ort 9. a

e ri ht hand head 13 is of similar form but is a apted to fit the convex surface of the article at the right hand end of the bundle. This head is also provided with a spindle 14 which fits into a sleeve 15 adapted to slidelongitudinally in the barrel 16 f the right hand head support 5.

ticles to be bundled one or the other or both of the heads are moved longitudinally to compress the stack or pile'of articles. In theconstruction:illustrated this result is secured by moving the right hand head. In the patent to Kbyesabove referred to this movement was secured by a screw which secured the desired compression but which was comparatively slow in its action. An important feature of this invention is to provide a means by which the compressing movement of the head'is secured quickly and by a single movement ofthe hand of the" operator, and a simple and preferred construction for effecting this result is illustrated.

A lever provided comprising a yoke shaped section 17, the legs-18 ofwhich straddle the barrel 16 of the head support,

and a handle section 19 which is made'of sufficient length to secure the requisite leverage when operated by hand; This lever is fulcrumed to the barrel 16 of the head support by a pin 20 passing transversely therethroughand held inplace by a cotter pin 21. A plurality of holes 22 are provided in the legs 18 for engagement with'the fulcrum pin 20. The lever is provided with a link con nection to the: head. This connection is effected by a pair of rods 23 mounted one at each side of the barrel 16 of the head support and pivoted at oneend at 24; to the left hand end of the sleeve 15, and pivotedat 'the other end at 25 to the legs 18 of the lever.

v These rods 23 are preferablym'ade in two sections threaded: together at 26 thus en ablingthe' length of the link to be adjusted.

When the head is in its retractedposition' the lever'handle 19 preferably stands vertically as shown in Figsrl and '2. When in this position the pile orstack of articles to be "bundled is placed between the heads and then the operator grasps the handle 19 and swings the lever about its fulcrum20 to the left thus 'proj ecting the head longitudinally" and compressing"longitudinally the pile or stack of" articles to be bundled. This movement is' accomplished by a single swing of the' handi Asfthej handle comes down to horizontal position the pivotal connection 25 passes the line running through the lever fulcrum 20 an'd the' pivot2 i connecting the link and-head, and-some portion of the ever and link structure such as the yoke-17 comes into contact'with some fixed portion of the machine such as the upper surface of the barrel 16 of the head support, and thus the head is locked in its projected position. hen the bundle has been wrapped. and tied this look is broken by raising the handle slightly and returning it or allowing it to return to its upright position. The extent of longitudinal projecting movement given to the head may be adjusted by setting the fulcrum pin 20 into one or the other of the holes 22 and also by adjusting the length of the links 23.

There is thus provided a simple, strong. and quick acting construction for projecting the head to compress the articles to be bundled, and one in which at the end of the compressing stroke of the lever the parts are automatically locked to enable the bundling to be performed.

The stack or pile of plates or other articles is supported in proper alinement with the heads by a mechanism similar in its general features to that illustrated in the patent to Keyes above referred to, but one in which the construction has been simplified. The articles are supported upon a pair of longitudinally extending supporting bars 26. These are arranged to support the articles at two widely separated points so that the articles are held in proper alineinent with the axis of the heads. They are made si multaneously adjustable in such a manner that they always remain parallel with the axis of the heads. but move toward and from the axis on substantially radial lines so that whatever the diameter or size of the articles may be they are supported at two similar or symmetrically disposed points. These supporting bars 26 are preferably hollow tubes or cylinders and are bolted to plates at their ends by the bolts 27 extending centrally therethrough.

At the right hand end of the machine the bed 1 is provided with a. rigid downwardly projecting bracket 28 and at the left hand end with a rigid laterally projecting bracket 29. A shaft 30 extends longitudinally of the the bed and is journaled in. the brackets 28 and 29. At its left hand. end. it carries a plate 31 and at its right hand end a plate 32 between which one of the bars 26 is bolted. The shaft 30 also carries rigid therewith adjacent the plates 31 and 32 respectively the gears 33 andv 34. The other but 26 is supported at its right hand end in a plate 35 mounted upon a trunnion 36 in the plate 28 and having rigidly connected thereto a gear 37 meshing with the gear 34:, while at its left hand end this bar is mounted in a plate'38 upon a similar trunnionhaving a similar gear meshing with the gear 33. The plate 32 is extended downwardly below the shaft 30 and'provided with a segmental slot 89 fitting over a screw bolt 10 in the plate 28. This screw bolt is referably provided with an operating han e 41. It will thus be seen that upon loosening the screw bolt 40 either bar 26 may be swung toward or from the axis of the heads and that thereupon because of the gear connection the other bar 26 will move in a similar manner and to a similar extent. Thus the bars may be brought, along substantially radial lines, into position to support articles, of any diameter in axial alinement with the heads. When the bars have been brought into proper position the are locked in place by screwing up the hot 40.

The operation of the machine otherwise is substantially as described in the patent to Keyes above referred to and as the placing in position of the wrapping paper and cords is fully described therein it is not here repeated.
